===Fiscal asymmetry===
{{See also|Basque Economic Agreement}}
The [[Political divisions of Spain#Decentralisation model|model of devolution]] is often termed ''asymmetric ''to express the fact that not all regions have the same powers. This is on the whole seen as advantageous; able to respond to diversity. However one aspect of this asymmetry is a cause of friction (eg in Catalonia), namely that the [[Basque Country (autonomous community)|Basque Country]] and [[Navarra]] can raise their own taxes and negotiate a transfer to Madrid to pay for common services and hence, unlike the other regions, do not contribute to fiscal equalisation across Spain.{{sfn|Keating|2007|p=22}} 

The [[Statute of Autonomy of Catalonia of 2006]] gave a similar power to Catalonia. However in 2010 the Constitutional Court disallowed the provisions and made it clear that to make the fiscal model in Catalonia like that of Navarra and the Basque Country would require an amendment to the constitution.{{sfn|López Bofill|2014|p=3}}
